The objective of this Phase I SBIR effort is to develop and demonstrate an advanced, deployable, high gain, active reflect array antenna for use in high data rate transmission to, from and among small spacecraft. While the antenna architecture proposed by AOE can be targeted for frequencies from below L-band to Ka-band and higher, AOE has selected X-band for a demonstration array for this proposed effort. Under the Phase I effort, AOE and LoadPath will focus on achieving an efficient deployable reflect array configuration and, within the trade space of reflect array architectures, will explore several approaches and perform the trade analyses in terms of performance, cost, size, weight and power. The results of this investigation will yield a high gain antenna architecture that will support future NASA and commercial small satellite communication operations. During the Phase I effort, the array deployment mechanism will be demonstrated with hardware while a complete beam-scanning reflect array antenna will be demonstrated with hardware during the Phase II effort.
Potential NASA Commercial Applications: (Limit 1500 characters, approximately 150 words) Small spacecraft communication systems must be increasingly robust, flexible and diverse to support a wide variety of stand-alone and interconnected missions used by NASA to conduct space science, Earth science and exploration of the universe. All NASA missions require communications ability and the technology proposed here will be a low-cost enabler to support higher data rate communications for small satellites by reducing the mass, stowed volume and achievable bandwidth and scan volume for a high gain antenna.
Potential NON-NASA Commercial Applications: (Limit 1500 characters, approximately 150 words) AOE?s commercialization strategy will focus on CubeSats and SmallSats and their use in the communication systems market. CubeSats, NanoSats and SmallSats are gaining increasing popularity as they allow a more practical and cost-effective way of getting into space as compared to conventional satellite payloads. One of the primary uses of satellite systems is for communication applications. As with military and government systems, commercial satellite communication systems are evolving toward the need for improved coverage, increased bandwidth, higher data throughput, and improved connectivity and will also need wide-band, multi-beam antennas. Commercial systems will require the antennas to be relatively low cost to be a practical system solution; hence the low cost, multi-beam-capable reflect array technology developed here should have direct relevance to future commercial systems.
Technology Taxonomy Mapping: (NASA's technology taxonomy has been developed by the SBIR-STTR program to disseminate awareness of proposed and awarded R/R&D in the agency. It is a listing of over 100 technologies, sorted into broad categories, of interest to NASA.)
